Answer: 3
Step-by-step explanation: This equation can be written as 4x+3x-4=17
We can now solve.
Moving the 4 to the other side (adding) and we get 21.
Now we have 4x+3x. Adding like terms, we get 7x = 21. Now we divide by 7.
X = 3.
The 5 - number summary :
Min____ Q1 ___ median ____ Q3 ____ max
7 ______ 9 _____ 12 _______ 15 _____ 18
Answer:
Hence, from the 5 number summary, about 75% of sons have fewer than 15 stylist.
Step-by-step explanation:
Explaining the table :
Minimum number of stylist salons have = 7
Maximum number of stylist = 18
Q1 = first quartile, (25 /100) ;About 25% of salons have fewer Than 9 stylist
Q2 = second quartile or median ; About 50% of salons have fewer Than 12 stylist
Q3 gives the 75th percentile value.
Q3 = third quartile (75/100) ; About 75% of salons have fewer Than 15 stylist
The number of mole of pure 11C (carbon-11) initially present is 0.2727 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation
Mole = mass / molar mass
With the above formula, we can obtain the number of mole of pure 11C. Detail below:
<h3>How to determine the mole of 11C</h3>
From the question given, the following data were obtained:
- Molar mass of 11C = 11 g/mol
- Mass of 11C = 3 g
- Mole of 11C =?
Mole = mass / molar mass
Mole = 3 / 11
Mole = 0.2727 mole
Therefore, the number of mole of pure 11C initially present is 0.2727 mole

Answer:
The question is not complete but from the flow of thought, the question seems to be about what your choice will be between option 1 and option 2.
The correct answer is
option 2
Step-by-step explanation:
The question is asking you to choose an option that pays more after 30 days. In other to determine the more beneficial option, we will compare both options and select the one that pays more. This is done as follows:
option 1: $60,000 per day, after 30 days =
60,000 × 30 = $1,800,000
option 2 = $5,368,709.12 after 30 days
From the total amounts after 30 days of the two options listed above, option 2 is higher than option 1 by $3,568,709. Therefore, option 2 is a better choice.
